ROLLER BEARING Filed Nov. 5, 1928 Patented Dec. 1 6, 1930 I i UNITED STATES'PATENT OFFICE I FREDERICK CAMERON cownurm, or eosronnnnemivn nonnnannnnme .lipplication filed November 5, 1928, Serial No. 317,257,- and in Great Britain November 25, 1927.

This invention has relation to roller bearings and the like, and. is also applicable to epicyclic gearing of the friction roller type;

, The invention has reference to roller bear- 6 ings and the like of the kind in which the inner and outer races and the rollers are conical. 1

The invention has for its object to ensure that the three members of the bearing always tend to assume a position in which they E have a common apex.

- The present invention comprises the combination with roller bearings and the like ofthe kind herein referred to and wherein the outerrace and the rollers are capable of movement longitudinallyin relation to the inner race,'of an abutment integralwith or mounted on the outer race to contact with the'broad endsof the rollers and means to 2 2O apply end thrust to the rollers in a direction to force their broad ends into contact with the abutment.

In order. that the invention, the nature V of which has been set forth, may be particularly described and ascertained, reference will now be made to the accompanyingsheet of drawings, on which t v Fig. 1 illustrates diagrammatically the in- -vention in its simplest form; and r Fig. 2 is a longitudinal sectional view of "epicyclic gearing embodying the'invention.

Referring to Fig. 1,

' A is the inner race whichis mounted on shaft or'carrier so as to be incapable'of I rotary and longitudinal movement in relation-thereto, Bis the outer race which is mounted so that it can move both in a rotary sense and longitudinally in relation to the inner race-A. Gis one of a set of rollers inraces'A B are conical and the rollers C are frustro-conical andall have a common apex D. The rollers G are subject to end thrust, T as by a spring E,-appliedto the small ends thereof. The outer raceB has an abutment f F around that edge towhich the broad ends 7 of the rollers C are directed, The thrust on the small ends of the rollers G is transmitte'd through the abutment F to'the outer race B so that the rollers Oand outerrace terposed between the-races A and B. Thecontained in pockets 15 and bearing through I a plate 16 on the flanged sleeve 12. By the sprlngs 14 and end thrust is applied to the rollers (I and'this end thrust is transmitted through the abutment F to the outer race B,

which, together with the rollers C is moved longitudinally in relation to the innerrace Auntil the rollers C are in running contact with the races A and B. In the left-hand portion of Fig. 2, the abutment F is shown as integral with the outer race B. The face of the abutment F opposite the ends of the rollers C is chamfered.

In the right-hand portion of Fig. 2, the abutment is constituted of a ring F chamfered on the face adjacent the broad ends of y the rollers C. The ring F is containedwithin a carrier 17 screwed into the outer race B. The ring F is rotatable in its mounting.

What I claim is 1. The combination with roller bearings and the like of the kind herein referred to, and wherein the outer race and the rollers are capable of movement longitudinally together in relation to the inner race, of an abutment on the movable outer race to contact with the broad ends of the rollers and means to apply and thrust to the rollers in a direction to force their broad ends into contact with the abutment.

2. Roller bearings and the like of the kind herein referred to as claimed in claim 1, wherein the abutment comprises a ring mounted in the outer race so as to be rotatable in relation thereto.

3. Roller bearings and the like of the kind herein referred to, the combination of an inner race, tapered rollers having a bearing on said race and an outer annular floating race embracing the outer peripheries of the said an outerannular floating race tapered to cor; 7 7

respond to the taper ol -the rollers and engag-v V ing the outer bearing of said rollers,the outer floating race having an abutment against rollers and bearing thereon and an abutment on said race'against which the rollers engage whereby the rollers and the floating race are longitudinally movable, o

4. A roller bearing and the like of the kind herein referred to, the combination of an inner tapered race, roller bearings oorrespondingly tapered andengaging the inner race,

which the large ends of the rollers engage, and means for pressing thesaid rollers in a direction toward their large ends. 7

a "5'. In a roller bearingand the like, the combination of an inner tapered race, tapered rollers engaging the said race and an outer annular floating race-tapered tocorrespond With the taper of the rollers and in engagement withtheir outer peripheries, wmeans pressing the said rollers in the direction of theirlarger ends, saidifloating race having an abutment in engagement adjacent their outer peripheries. 4

6. The combination with roller bearings and the like of the kind herein refered to, and wherein the outer raceandthe rollers arecapableof movement longitudinally in relation to the inner race, of anabutment onthe outer race to contact with the rollers and means to .applyend trust to thejrollers in a direction to force them into'contactwith the abutment.
